-- | PURPOSE  : This script will list all workspaces and which workspace is the |
-- |            current workspace. You are then prompted for the name of the    |
-- |            workspace to unfreeze. The script then unfreezes the workspace. |
-- | NOTE     : As with any code, ensure to test this script in a development   |
-- |            environment before attempting to run it in production.          |
